Patients with multiple sclerosis (MS) who are treated for chronic cerebrospinal venous insufficiency with minimally invasive endovascular treatment may experience significant symptom relief and short-term improvement in their quality of life.

So say the authors of two studies presented at the Society of Interventional Radiology’s 37th Annual Scientific Meeting in San Francisco. Results of those studies suggest that for many people with MS, minimally invasive interventional radiology treatments can provide effective palliative therapy.

In one study, researchers analyzed questionnaire responses from 192 patients with various forms of MS. The questionnaire reviewed key quality of life components, including changes in physical abilities, health perception, energy and fatigue, sexual function, emotional well-being, cognition, and pain, said Meridith J. Englander, MD, one of the study’s co-authors.

More than 75% of those with relapsing remitting and primary progressive MS reported significant physical improvements. Mental health scores also improved in most of those studied.

A second study—a retrospective review of 105 angioplasty procedures—produced similarly encouraging results. Over half reported at least some symptomatic improvement; while 38% reported no improvements. Those with relapsing remitting MS reported the most favorable results.
